But Judge Carol Atkinson, who did not say what diseases the immunisations related to, said the woman had a 'paranoid view of the world'.

She added: 'The mother has refused her consent on a number of different bases; that the vaccines contain pork gelatine is the most recent objection.

'It transpired that the ones proposed do not. Having been shown her fears are unwarranted she has agreed that the children can have the necessary vaccines.'

Judge Atkinson, who did not identify the family, added that she made the order to stop the mother changing her position and withdrawing her consent at a later date.

The issue was brought before the court after social workers asked the judge to make rulings on a number of welfare issues including where the children should live.

The children’s parents, both in their twenties, had separated and they had been living with their mother in London.

But the judge heard that the youngsters had been taken into police protection after concerns were raised about their care.

Judge Atkinson, who said the mother was emotionally volatile and had displayed aggressive behaviour, concluded that the youngsters should live with their Somalian-born father, who was also based in London.

She said he would have support from social workers and added that the children should stay in contact with their mother.

The judge said the council had taken action after neighbours complained of a woman shouting abuse at children and telling of persistent crying.
